MOTOR-VEHICLE.

Specification of Letters Patent.

Patented Apr. 5, 1921.

Application filed November 17, 1917. Serial No. 202,507.

T0 all whom t may concern Be it known that I, FRANK J. DRUAR, a

, citizen of the United States, and resident of Detroit, `Wayne county,State of Michigan, have invented certain new and useful Improveniente inMotor-Vehicles, of which the j ject in a straight line forwardly or insome cases be directed downwardly slightly but to the same extentforboth lamps where two lamps are used.` lt is not a possible manufacturingjob to so make the lamps and their brackets that whenlitted to thevehicle the lamps will be always in exactly the right place andheretofore the lamps have been adjusted on the vehicle by bending thelamp brackets or supports slightly to bring the lamps into the correctposition. Inl some cases these lamp supports have been made so strongand rigid that this adjustment of the lamps after they are on thevehicle has become a difficult matter and itis one of the objects of thepresent inven* tion to rovide for an adjustment of the lamp reflectorand the bulb carried thereby after the lamp has been positioned on thevehicle thus dispensing with the necessity of! adjusting the entire lampbody.

j Another object of the invention isto so mount allamp reflector withinthe body of the lamp that'the reflector may be adjusted independently ofthe lamp body. Such adjustmentmlis sometimes desirable in order that therays of light may be directed slightly downwardly without tilting thelamp body for that purpose.

Other objects of the invention will appear from the followingdescription taken in connection with the drawings which form a art ofthis specification, and in which:

*igure l is partly a sideelevation and .partly a` vertical'sectionthrough a motor vehicle lamp embodying this invention;

Fig. 2` is a perspective detail view of a portion of the reflector ofthe lamp shown in Fig. 1; and` i Fig. 3 is a somewhat enlargedfragmentary view of` another form of the invention.

vReferring to the drawings, represents the main body part of a lampwhich is particularly adapted for motor vehicle use. It 1s .shown asprovided with lugs 11, there being one on either side of the lamp, bywhich 1t is supported upon a lamp bracket 12 on a motor vehicle. Thelamp shown is specially designed for the use of an electric bulb andwires 13 lead through the lamp body at 141 to a socket shown in dottedlines atl within the lamp body. A bulbv 16 is shown as mounted in thesocket and the latter issupported in a reflector 17 which is mounted inthe lamp. Said lreflector is preferably of parabolic form and at itsperiphery there is a flange 18 by which it is supported in the lampbody.

The lamp body l() is also of somewhat parabolic form and its peripheryis spun out radially as at p19 and then bent back upon itself in theform of an inwardly eX- tending flange 2O as shown in Fig. 1. Thisinwardly extending flange 20 carries a reflector support 21 which isdetachably secured to it as by a series of screws 22, and a packing ring23 is shown as secured between the attaching flange 24 of the support 21and the flange 20 above referred to. The lamp is provided with a frontcover 25 which is shown as hinged to the body at the top as at 26 and asprovided with va detachable fastening 27 at the bottom of the lamp. Thiscover is of any suitable built-up construction, being provided with alens 28, and when in vclosed position as shown in Fig. 1 it is drawn intight against the packing ring 23 so that the lamp is thereby madewater-tight. V j

y For the purpose of permitting adjustment of the lamp reflector 17relative to the body of the lamp, as above suggested, the

`Hector is placed in the lamp body these two surfaces are broughttogether as shown in Fig. 1.` `Preferably the spherical surfaces when inposition are formed about a center which is adjacent to or substantiallywithin the lamp socket 15 above referred to so that j openings 33somewhat larger than theV Y shanks of the screws 32 but smaller than theheads thereof so that these screws may be inserted through Vthe openings33 and into the ring 31 for therebyl securing the'reflector in itsadjusted position. j

From this description it will be understood that by loosening theseveral screws 32 the reflector may be manually adjusted on thespherical surface' 30 to the position desired for the best lightingeffect and the screws may then be tightened to secure the reflector tothe lamp in that' position.

In Fig. 3 the reflector 17 is shownV as having its flange 18 secured tothe inner face 30L of the support 21a instead of to the outer face asshown in Fig. 1.A In this case also the ring 31a is secured to thereflector flange 18 instead of to the support 21 as shown in Fig. 1.Openings 33a are formed in the supportV 2'1a and screws 32a operate tosecure the reflector inadjusted position as in the construction shown inFig.' 1. v

In this construction shown in Fig. 3 it will be understood that inassembling the various parts the reflector 17' must be first mounted onythe support 21qd before the latter is secured to the body 10 of thelamp. However, the adjustment of the reflector may be lmade -with thesame ease asin Ythe construction shown in Fig. 1 after the lamp ismounted yupon the vehicle or the support.

.Y Thebody 10 vof the lamp shown in Fig. 3

' is formed somewhat differently from that of Fig. 1 so far as itsconnection with the support 21a is concerned. It has no radial flange 19but its peripheryis formed with an inwardly extending flange'20a towhich the lsupport 21a is directly secured as by the screws 22a. Thesupport 21a is formed with a radial flange 311 to which is secured apacking ring 23, screws 35 passing through the flange 341 and ring 23ainto a ring 36 provided for the purpose. The hinge 26 of the Y lamp issecured to this ring36 and the front eover'25 and other parts of thelamp are the the same as in Fig. 1.

It will beunderstood'further that my invention is notV limited to thedetails of construction shown and other .forms may be used withoutdepartingl from the spirit or scope of the invention. Y

'Having thus`V described my invention, whatgI claim and desire to secureby Letters Patent is 1. 'A lamp Vhaving Va reflector provided with aspherical rim portion disposed at an angle to the main body portion ofthe reflector and lying forward of the lamp bulb, a support for thereflector, means of engagement between such support and rim portion, therim portion of said reflector being adjustable on said support about thehorizontal axis of the lamp body.

2.
